Once you get the venom-x gun start using it! Let your team know that you need the achievement and let you grab the ammo for it to keep shooting. Once you land in the final breeder stage you can kill a lot of the smaller cryps really easy with the Venom-x to help tally up the number. If you want help hmu in xbox360 and ill help you get it.

personally i never use the venom x. and with seeing the new map coming out i probly wont even aim for the achievment till the new map comes out since it has upgrades to it. but ive heard of people getting the achievment from a few games of using it

has to be done in one game ...i did it playing solo or if you play in a group stay by the electric trap on top thats where most of the ammo drops...best gun in the game hands down, not only does it kill hunters in one shot but it lingers and gets stuck to aliens and kills them slowly ....i love the venom x just wish there was more ammo for it

If there was more ammo though, they'd have to make the aliens harder to kill, making the Venom-X not as great or useful as it currently is. If you had lots of ammo for it, everyone would just use that, causing it to become way overpowered. I'd rather it stay like it is.
